I-IORSESI-IOE ATTACHMENT.

To all whom it may concern:

Be it known that I, NICHOLAS A. BENDER, citizen of the United States, residing at Clayton, in the county of St. Louis and State of Missouri, have invented certain new and useful Improvements in Horseshoe Attachments, of Which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in horse-shoe attachments; and it con sists in the novel details of construction more fully set forth in the specification and pointed out in the claims.

In the drawings, Figure l is a side elevation of a horses hoof with a shoe having my invention applied; Fig. 2 is a top plan of the attachment showing the shoe in dotted outline in proper relation thereto; Fig. 3 is a front elevation thereof, with the shoe in dotted outline; Fig.4 is a sectional detail on the line 44 of Fig. 2; Fig. 5 is a sectional detail on the line or lg. 2; and Fig. 6 is a section similar to Fig. 5, showing a washer in conjuiui-tion with the pointed calk, as aoplied to a shoe partially worn down.

The object of my invention is to provide a calk attachment for horse shoes which may be temporarily secured to the ordinary shoe on special occasions, such as where the animal is to travel over ice, snow and slippery roads, the attachment being readily removed from the shoe when the latter can be utilized for general service.

The invention resides in structural details the advantages of which will be apparent from a detailed description thereof which is as follows Referring to the drawings, S, represents an ordinary shoe secured to the hoof H of the animal as usual, the shoe being provided with a toe calk If and heel calks 71, h.

Adapted to bridge or span the space across the shoe at the base of the inner curved edge of the shoe, and engaging said edge on each side of the central longitudinal axis of the shoe, is a central wall or abutment 1 of substantially the shape as shown, said abutment having extending outwardly therefrom at each end and from the bottom thereof, the brackets 2, 2, which in turn terminate in the upturned arms 3, 3. The ends of the abutment or Wall 1 imme- Specifioation of Letters Patent.

diately over the brackets 2, 2, are provided with overhanging formations or lips 4, 4, which, when the attachment is in place 011 the shoe, overlap the upper face of the shoe resting on the brackets, the outer curved edge of the shoe bearin snugly against the rear vertical basal portions or walls a, a of the arms 3. The brackets 2, 2, are each provided with an annular depression or basin (Z to receive the circular head 5 of the conical calk 6, the calk having a central cylindrical body portion 5 received by a circular opening formed in the bracket. Thus the shoe S rests directly over the head of the calk when the attachment is in position on the shoe.

As best shown in Figs. 1, 2, 3, and 4, the arms 3 have sufficient curvature imparted to them, so that when the device is in place on the shoe, (Fig. 2) the arms 3 are in close proximity to the front inclined portions of the hoof. The free ends of said arms are provided with screw holes 0, the axes of which are at an incline to the general plane of the shoe, but substantially at right angles to the face of the hoof. Into these holes are screwed the set-screws 7, and when the latter are driven home against the hoof, the ends of the abutment 1 are drawn tightly against the inner curved edge of the shoe, which rests snugly under the lips 4, 4, and between the walls a, a (of the arms 3, 3) and terminals of the abutment 1. The diagonal disposition of the screws likewise serves to draw the attachment in an upward direction, thereby drawing it firmly against the bottom of the shoe. The hollow of the hoof readily accommodates the bridge wall or abutment 1 as shown by dotted lines in Fig. 1.

The height of the wall a corresponds substantially to the thickness of the shoe, the bottom of which rests on the brackets 2 (directly over the calkheads 5) and Whose upper surface engages the bottoms of the lips 4, 4, there being a snug engagement between the parts referred to. Should for any reason the shoe wear down, or a thinner shoe be worn by the animal than the particular attachment was designed for, the driver may simply interpose a washer w between the head 5 and the bottom of the pocket d as shown in Fig. 6, thus raising the head 5 sufficiently to elevate the shoe resting on it, into firm contact with the bases of the lips at, at, so that no possible play could take place between the parts. For it must be remembered that the opposite faces of the shoe should always be tightly gripped between the lips 4:, 4E, and the brackets 2, 2, (or the calk heads 5 on which the shoe in a large measure rests).

To apply the attachment, the screws 7 are first unscrewed sufficiently to allow the arms 3, 3, to clear the lower edge of the hoof, the device being passed under the front of the shoe in the position shown in Fig. 2, the inner curved edge ofthe shoe being first brought under the lips 4, at, after which by a slight rocking or oscillation of the attachment to bring the free ends of the arms 3, 3, well against the hoof, the parts are in position to have the screws 7 driven home in the manner indicated. The pointed ends of the screws will penetrate the soft material of the hoof a suitable distance, thus preventing any possible displacement of the attachment while the latter is in service. The calks are sufliciently long and pointed to enable the animal to secure a firm purchase on a slippery or icy surface, which makes travel for the animal comparatively easy. By loosening the screws 7, the device may be instantly detached from the shoe as is obvious from the drawing.

Having described my invention, what I claim is 1. A horse-shoe calk attachment comprising a member mounted across the base of the inner curved edge of the shoe and having lips overhanging the upper face of the shoe,-

2. A horse-shoe calk attachment comprising a member mounted across the base of the inner curved edge of the shoe and having lips overhanging the upper face of the shoe, brackets extending outwardly from said member and engaging the bottom of the shoe, calks carried by said brackets and adapted to maintain the shoe in close contact with the lips, terminal upwardly extending arms at the ends of the brackets provided with basal wall formations for engaging the outer curved edge of the shoe at points opposite the lips aforesaid, and set-screws mounted at the free ends of the arms and at an incline thereto for engaging the hoof.

In testimony whereof I aflix my signature, in presence of two witnesses.
